Abstract

Bei einem Pumpenaggregat, insbesondere für Geschirrspüler, be­ stehend aus einer Pumpe (1) und einem gleichachsig an diese ange­ bauten Asynchronmotor (2), der wenigstens an der einen Stirn­ seite seines Rotors (23) ein Radiallüfterrad bildende Lüfter­ flügel (22) aufweist, ist jedem vorhandenen Radiallüfterrad eine relativ zum Stator (7) und der Statorwicklung feststehende Luft­ leitvorrichtung (18) zugeordnet, die zusammen mit dem das Lüfter­ rad in radialem Abstand umgebenden Wickelkopf (12) der Statorwick­ lung zumindest im Übergangsbereich der Wickelkopfoberfläche von der Innenmantelfläche (13) zur Außenmantelfläche (14) einen Luft­ leitkanal (19) bildet. Dieser Luftleitkanal (19) lenkt die nach dem Austritt aus dem Lüfterrad gegen die Innenmantelfläche (13) des Wickelkopfes (12) gerichtete Kühlluft um das freiliegende Wickelkopfende herum. In a pump unit, especially for dishwashers, be standing from a pump (1) and an axially attached to this built asynchronous motor (2), at least on one forehead side of its rotor (23) a radial fan forming fans has wing (22), each existing radial fan is one air fixed relative to the stator (7) and the stator winding guide device (18) associated with which the fan radially surrounding winding head (12) of the stator winding at least in the transition area of the end winding surface of an air from the inner surface (13) to the outer surface (14) Leitkanal (19) forms. This air duct (19) directs the the exit from the fan wheel against the inner surface (13) the winding head (12) directed cooling air around the exposed Winding end around.
